To all 'whom 'it may concern:

Be it known that I, URIAH G. PoTTs, a resident of Martinsbur in thecounty of 'Berkeley' and State of gVest Virginia, have inventeda new anduseful Improvement in Rails; and I do hereby declare the following tolbe a full, clear, and exact description thereof. V

My invention relates to rails, and has special reference to the class ofrails for use on railroads, traction roads, etc. f

The object of my invention is to provide a rail which can easily andquickly be renewed in case of wear or breakage without disturbing asolid track, and one which will always be rm and rigid when in positionand use.`

My invention consists, generally stated, in

the -novel arrangement, construction and' combination of parts, ashereinafter more specifically set forth and described and particularlypointed out in theclaims.

To enable others skilled in the art to which my invention appertains, toconstruct and use my invention, I will describe the same more fully,referring to the accompanying drawing, in which z- Figure 1 is across-section of a track employing my improved rail. Fig. 2 alongitudinal section of ay track showing a side elevationof the rail.Fig.- 3 is an enlar ed cross-section of the rail. Fig. 4 is a lke viewshowing another form of the rail. Fig. 5 is an end view of another formof the supporting base.Y Fig. V6 is a cross-section of another form ofbase.

Like symbols of reference herein indicate like parts in each of thefigures of the draw` ing.

As illustrated in the drawing, 1 re resents the base section of theimproved rai which is intended to be secured in position by beinembedded in the concrete a or can be secure upon theties of the road-bedaccording to any of the approved manners of securing rails. The ends ofeach of the base sections 1 are cut square across, so that they willabut against each other when the rail is laid down in order that therail may be built up in position without diiiiculty. The 'baseange 2 ofthe section 1 .is of the usual shape and size, with the web 3rising upfrom the same for some distance, and the up r end'of said web isisplitor openedl out Vto orm a channel Abase 4, which thereby forms a.- space5 and the vside-webs 6. This space or hollowed out portion 5 is4intended to receive the tongue or flange with which the tread sectionis supplied and-the tops or upper ends of the webs 6 arerounded, as at 7in order to conform to the under face ofthe upper part or head of .thetread section. v

Y The tread section is shown at 8, and is' rovided with the tongue orHange 9 exten ing down from thev head 10 thereof, which flange' 1s ofthe size and shape tofit in and conform to the space 5 in the channelbase 4 ofthe base-section 1. These tread sections are out square acrossattheir ends, and the under faces 11 ofthe head portions rest againstthe 'rounded ends 7 onl the webs 6.

formed in the webs 6 and tongue 9 respectively on the base sections andtread sections, and. such ,keys are 'heldin place b means of nuts 15engaging with the ends o said keys.-

These keys 1-2 are provided with an inclined upper face for engagingwith a. likeface in the holes 13011 .one of thewebs 6` and with a "like-face on the holes-14 in the tongue 9,

While a-strai ht portion is formed on said keysforsai nuts and forfitting in like holes inthe other holes 13 in the other web 6, .so thatsaid arrangement will hold the two sections of the 'rail together in asolid and rigid manner by drawing the tongue downward and will preventany movementof the sections or vibrationor noise of one part upon theother.

In layin the rails 1 for forming a track such as is s own in' Fig. 1, atie-beam 16 eX- tends between such rails, being connected to -the web 3of the base sections 1 by means of bolts 17 passing throughv said weband` through iianges 18 on said' beam, and such beam is embedded in the'concrete a around therails. n

In the use of the rails for traction purposes, the inner web 6 on thebase sections 1 is .provided with zin-inwardly projecting liange 19 forforming a girder rail to act as a ve-4 I. in the base sections,a s isshown in Fig. 4.

The base section 1 can also be provided with track 4flange 19 on bothsides ofthe webs i 6 on the same to lform a double 'girder rail,

:as shown in Fig,v v and.- the space 5 can 'extend entirely through theweb 3 of the base section l, asl shown in Fig. 6. Itwill thus lbe seenthat the sections of'my improved raged by the Contact of there ith.

rail are of such a shape and'form that they may be rolled in an ordinaryrolling mill,

vvand thusv produced without any unnecessaryl or additional cost, andwhen soproduced and properly perforated to receive the wedgebolts, theycan be readily 'laid'upon theroadbed and secured thereon as may bedesired. The base sections may be made of cheaper,

metal than the tread sections as the latter alone are subjected tobeingworn or damthe traveling wheels The tread sections are' inade tobreak joints with thev joints in the base sections if ,desired, ,andwhen they are finally bolted to place lther'ail is quite as rigid, firmand sev-cure at allpoi'nts as if'made in' a. single piece, and this, ofcourse, Will occur throughout the entire length of the vrailconstruction.` The concrete a can be provided withl are not required tobe removed from the as they will not be liable to breakage, -while' '35.any'- of the tread sectionsv may beremoved` road-bed, and will seldomneed repaving,

' and replaced when-necessary, 'and any such.

section when removed may be cut and re-v placed in divisions, ifdesired, it being onlyl necessary to have the holes Properly punchedthrough the flange and properly spaced. It Will thus be obvious that therail may easilv and quickly'be repaired upon the 'tread sections inplace.

road, as all the. joints are of extreme sim plicity and .will not getout of order.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A rail having a base section formed with a channel web and a girderflange eX- tending out from said web, .a tread section having a tonguefitting within said web, and wedge #shaped bolts passing through in?clined faced4v holes in one of said web portions and tongue and througha straight hole in the other web portion by astraight portion thereon,'for holding said base and tread sections in place.

2. A rail having a base section formed with a channel web havinginclined interior sides, a tread section having an inclined sided tonguefitting within said web, and wedge shaped boltsv passing through inielined facedholes in one of said web ortons and tongue and through` astraight hole in the other web portion by a straight portion thereon,for holding said base and 3. A rail having a base section formed vvlth achannel web having inclined lnterioi" sides and a glrder flangeextendlng out from Asaid web, a tread section having an inclined sidedtongue fitting within said web, and
